South Australia public transport
The Adelaide Metro General Transit Feed (buses, trains and trams in metropolitan Adelaide, plus the regional coach operators the same feed carries, such as Stateliner) as GeoParquet, JSON and vector tiles, rebuilt weekly by milleleaf/sa-transit, with a snapshot of the GTFS-realtime feeds (vehicle positions, trip updates and service alerts) every 15 minutes. Every table, row and field of the source is kept.
| File | Holds |
|---|---|
gtfs/<table>.parquet |
Every table of the feed (agency, routes, trips, stop_times, stops, shapes, calendar, calendar_dates, transfers, booking_rules, feed_info, and any table added later), every column as text, exactly as published |
release-notes.txt |
The feed's own release notes |
stops.parquet |
GeoParquet: every stop, every column, with a point geometry |
route-shapes.parquet |
GeoParquet: one row per route and shape a trip uses: every route column, shape_id, trips, points, shape_dist_traveled, and the shape as a line |
stops.json |
GeoJSON of every stop, every field |
routes.json |
Every route, every field, with its shape_ids and trips |
transit.pmtiles |
Vector tiles, layers routes and stops, zooms 4 to 14; every feature is in every zoom |
index.json |
Row counts, the tables, and the feed's feed_info (version and validity dates) |
Live feeds (bucket only)
On the bucket, refreshed every 15 minutes (GitHub may start a run
late or skip one, so the history has gaps). Three GTFS-realtime feeds, each as <feed>:
<feed> |
Feed | Daily Parquet: one row per |
|---|---|---|
vehicles |
vehicle positions | vehicle per snapshot (GeoParquet, a point per vehicle) |
trip_updates |
trip updates (predicted arrivals and departures) | trip per snapshot; stop_time_updates counts its stop predictions, which are in entity |
alerts |
service alerts (disruptions, stop changes) | alert per snapshot |
| File | Holds |
|---|---|
live/<feed>.json |
The latest feed decoded to JSON, every field, including the feed's own vehicle extension (air_conditioned, wheelchair_accessible as tfnsw_vehicle_descriptor on every vehicle descriptor) |
live/<feed>.pb |
The same feed as received (protobuf) |
live/<feed>-YYYY-MM-DD.parquet |
Every entity in every snapshot of that UTC day, with the main fields as columns and entity, the full entity as JSON |
snapshot is the feed's own header timestamp, and the day is taken from it. On 2026-10-11 the service alerts feed's header
timestamp was Adelaide local time written as if it were UTC (10.5 hours ahead during daylight saving), while the other two
feeds were in true UTC; it is kept as published.
The bucket keeps the current month (plus the previous one until it is archived). The full history is on Kaggle, one
dataset per feed and month, never changed once created: helenkwok/sa-transit-vehicles-YYYY-MM,
helenkwok/sa-transit-trip-updates-YYYY-MM and helenkwok/sa-transit-alerts-YYYY-MM
(e.g. https://www.kaggle.com/datasets/helenkwok/sa-transit-vehicles-2026-10).
manifest.json lists every file's sha256, the counts and the sources of the latest bake. Coordinates are WGS 84 as
published in the feed.
